FEATURES OF COPPER, NICKEL AND COBALT BEHAVIOUR DURING THEIR DEPOSITION FROM AMMONIA - CARBONATE SOLUTIONS BY SULFURIC COMPOUNDS

摘要

The regularities of copper, nickel and cobalt deposition process from ammonia-carbonate solutions by ammonia polysulfide and lime-sulfur solution are studied It is shown that extraction of 100 percent of copper, 78 - 82 percent of cobalt and 10 - 15 percent of nickel is reached at temperature level as much as 80-100 deg C and with sulfur consumption makes 1,4 - 1,6 mol from solution containing 80 g/dm~3 of NH_3 and 45 g/dm~3 of CO_2.
